Is Optimum Aminos legit? What the records show

We have tracked Optimum Aminos since Sep 2026 and follow 10 of their products. Prices run from $25.00 to $70.00. On their own certificates, 14 of 20 measured vials are more than 3% over or under the amount on the label, and 0 of 21 purity results fall below the 99% they advertise.

Check it yourself: find the report number or QR code on a certificate and look it up on the lab's own website.

We have not sent a Optimum Aminos product to an independent lab yet, so these 40 points are locked. The lab report will go on this page when we do.

Reviews6.4 / 20Good rating, few reviews

External review sites: ★ 4.4 ± 0.1 average, from under 50 reviews. We show a range because sites round their ratings differently.

That gives 6.4 of 20.

Community4.5 / 15Little or cautious talk

Forum and Reddit talk is thin or cautious. Nobody has left a review on Peptide Scanner yet.

That gives 4.5 of 15.

Certificates18.5 / 2510 of 10 peptides covered

Publishing: 12.7 of 15. We hold 45 lab certificates from their website, naming Freedom Diagnostics. We found 0 of the 45 on the issuing lab's own website (not every lab has a public lookup). 10 of the 10 peptides we track have a matching certificate from an independent lab (any size counts). 0 of the 45 certificates include a contamination test (endotoxin, sterility or heavy metals). 2 of 11 dated certificates were issued in the last 6 months. Newest: Jun 2026 (4 months old). Oldest: Feb 2026. 5 more have no readable date.

Claims match: 5.8 of 10. Their own certificates against their claims: 6 of 20 measured vials are within 3% of the label (14 overfilled); 0 of 21 certificates fall below the 99% purity they advertise.

Their claims against their certificates: 14 of 20 measured vials off label, 0 below the 99% they advertise.

A certificate is the shop's own document. It is not our test.

How this is checked
Vial content
Measured net peptide content against the size on the label. Within ±3% is on label, 3 to 10% is off label, beyond ±10% is a major deviation (under- or overfilled). When a certificate weighs several vials of the batch, the vial farthest from the label is the one judged, and with several purity results the lowest counts. Blends are only checked when the certificate lists each component.
Purity
HPLC purity on each certificate against the purity the supplier promises site-wide on its own website. Up to 1 point below the claim is amber, more than that is red. Only a direct promise counts (“99%+ purity guaranteed”); explanations of what purity means, one product's figure and page code are not treated as a claim. A certificate that reports only a bound (“>99%”) is judged only when the bound meets the claim, and a specification line is never read as a result.
Whose certificate
A certificate is only read once our client-identity review has looked at it, and one issued to a different company is left out. A certificate issued to the company that runs the supplier's own website counts as the supplier's. A file hosted on another supplier's website is not counted for this one. Only peptide certificates are read: bacteriostatic water, acetic acid and other diluents are left out, and so are product data sheets, which state a specification rather than a batch result.
Main impurity
Shown when the certificate itemises it: a named impurity (TFA, deletion sequence, oxidation…) or the largest secondary peak in the HPLC peak table. Most certificates report only a purity figure, so the rest of the sample is not itemised.
Score
These checks are 10 of the 25 certificate points: vial content 7 (full credit within ±3%, half up to ±10%, none beyond, over- and underfilled alike), purity 3 (98% is the bar when a supplier advertises no figure). Fewer than 5 readable results gives half credit rather than a guess.
Source and limits
These are the supplier's own published certificates, read automatically from the PDF or image. Janoshik results tables are read twice from the image, cell by cell, and a figure the two readings disagree on is left out rather than guessed. A certificate covers one batch on one date. We have not tested these batches ourselves.
